Backed by Hydraulic Cartridge Technology, these innovative patented tappets feature a self-contained hydraulic cartridge housed inside a thick wall lifter body. The hydraulic cartridge holds a smaller volume of oil that is less affected by aeration, allowing for those covetably consistent bleed-down rates. With a stiff lower body, the Roller Lifters reduce body distortion and further promote consistent hydraulic performance.
